英文摘要：

It is vital to determinate orbit and attitude of spacecrafts accurately. A method to determinate the orbit and attitude of spacecrafts by CCD image sequence and ground control points is proposed. Then the algorithm based on quaternion is given. Finally, the precision of the whole algorithm of this paper is proved by the simulations, and the algorithm is also valuable for some precise orbit and attitude determination.
